  • How to Invoke iPhone Maps for Directions with Current Location as Start Address

    - by eriaac
    Hi all. I know it's possible to start the iPhone maps application by calling openURL on a google maps URL with parameters saddr and daddr with location strings or LatLong (see ex. below), but I'm wondering if it's possible to make the start address be the "Current Location" maps bookmark so that I can use the maps app's location handling code. My Google search has been pretty fruitless. ex: [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat: @"http://maps.google.com/maps?saddr=%@&daddr=%@", myLatLong, latlong]]]; Except with something to invoke the current location bookmark in place of myLatLong. Thanks!

  • Moving a Ball on iPhone

    - by Chandan Shetty SP
    I am using below formula to move the ball circular, where accelX and accelY are the values from accelerometer, it is working fine. But the problem in this code is mRadius(I fixed its value to 50), i need to change mRadius according to accelerometer values and also i need bouncing effect when it touches other circles please send your answers ASAP... I am waiting. float degrees = -atan2(accelX, accelY) * 180 / 3.14159; int x = cCentrePoint.x + mRadius * cos(degreesToRadians(degrees)); int y = cCentrePoint.y + mRadius * sin(degreesToRadians(degrees)); Here is the snap of the game i want to develop. http://iphront.com/wp-content/uploads/2009/12/bdece528ea334033.jpg.jpg

  • What is the exact rule of jQuery's animate() parameters?

    - by Jian Lin
    jQuery 1.4.2's animate() API spec is .animate( properties, [ duration ], [ easing ], [ callback ] ) but it seems that we can supply duration, callback, and no easing .animate({left: '+= 100'}, 600, doThis) and it will work. But if we supply easing and callback and no duration .animate({left: '+=100'}, 'swing', doThis) then the easing won't be taken into effect. So what exactly is the API supposed to be?

  • Attachment_fu: can't disable :partition option

    - by Nathan Long
    I'm trying to use the Attachment_Fu plugin in a Rails project, and want to customize the paths where uploaded files are saved. The documentation shows this option: :partition # Whether to partiton files in directories like /0000/0001/image.jpg. Default is true. (The 0001 part is an ID from a table.) I don't want that, so I set the partition option to false, like so: class Photo < ActiveRecord::Base has_attachment :content_type => :image, :storage => :file_system, :max_size => 500.kilobytes, :resize_to => '320x200', :thumbnails => {:thumb => '100x100>' }, :partition => false validates_as_attachment end ...but the :partition => false option has no effect. Has anybody else encountered this problem? How did you fix it?

  • Programatically WPF Fade In (via extension methods)

    - by Dinis Cruz
    I'm trying to write a simple (stand alone) C# extension method to do a Fade-In of a generic WPF UIElement, but the solutions (and code samples) that I found all contain a large number of moving parts (like setting up a story, etc...) For reference here is an example of the type of API method I would like to create. This code will rotate an UIElement according to the values provided (fromValue, toValue, duration and loop) public static T rotate<T>(this T uiElement, double fromValue, double toValue, int durationInSeconds, bool loopAnimation) where T : UIElement { return (T)uiElement.wpfInvoke( ()=>{ DoubleAnimation doubleAnimation = new DoubleAnimation(fromValue, toValue, new Duration(TimeSpan.FromSeconds(durationInSeconds))); RotateTransform rotateTransform = new RotateTransform(); uiElement.RenderTransform = rotateTransform; uiElement.RenderTransformOrigin = new System.Windows.Point(0.5, 0.5); if (loopAnimation) doubleAnimation.RepeatBehavior = RepeatBehavior.Forever; rotateTransform.BeginAnimation(RotateTransform.AngleProperty, doubleAnimation); return uiElement; }); }

  • Disable page cache on a specific page

    - by David Brunelle
    Hi, Not sure if I really am on the right forum, but if not, just tell me. I have a page that is coded in ASP (not .net) which is used to send email. We are currently having a problem in which the page seem to be sent twice sometime. Upon checking, we found out that those who have this problem are coming from big organisation, so it was suggested that their server might cache the file for some reason. I would like to know, is there a way in HTML (or ASP ) to prevent that from happening ? Or is it in IIS that we must set this up ? Thanks,

  • Can I animate a radial gradient in iPhone?

    - by user364782
    I would like to animate a radial gradient to shrink and grow the inner radius, as if it were pulsing. Right now I'm rendering the gradient with CGGradient, but I'm not sure how to animate it. I've seen this topic http://stackoverflow.com/questions/1819311/can-you-animate-gradients-using-quartz-in-an-iphone Which explains how animate a linear gradient with CAGradientLayer, but it doesn't seem like this will draw a radial gradient. Is there an easy way to animate a CGGradient, or some way to create a radial gradient CAGradientLayer? Any thoughts are appreciated.

  • How to disable back button in browser using javascript or any script

    - by user225269
    Im using wamp server for my php scripts. And Im having difficulties on the logout code. Every time I click on the logout link and then click on the back button on web browser it still shows the page which can only be access by the user who is logged in. I have this code at the beginning of the index.php which is called by the log out link to destroy the session: <?php session_start(); session_destroy(); ?> And I have this at the beginning of the user page: <? session_start(); if(!session_is_registered(myusername)){ header("location:login.php"); } ?> I don't know why the userpage can still be access after the user has logged out. So I'm thinking of disabling the back button when the user has logged out. Please help.

  • MediaElement seems to disable lock screen when playing a video

    - by CrossProduct
    I am working on an application that plays a video using the MediaElement component. Now, I would like that if the user is idle, the lock screen appears, as configured by the user in the Settings of the device. If I don't play a video, the lock screen indeed appears. But, when a video is playing no lock screen appears. I cannot find any information on this. Currently I set the idle detection modes like this: PhoneApplicationService.Current.ApplicationIdleDetectionMode = IdleDetectionMode.Enabled; PhoneApplicationService.Current.UserIdleDetectionMode = IdleDetectionMode.Enabled; I am a bit lost now. The only solution I can think of is running a timer myself and stop the video playback after a certain time. (but there seems to be no API calls to receive the configured lock timeout.) Any suggestions are welcome, thanks.

  • Why is my simple python gtk+cairo program running so slowly/stutteringly?

    My program draws circles moving on the window. I think I must be missing some basic gtk/cairo concept because it seems to be running too slowly/stutteringly for what I am doing. Any ideas?

  • JavaScript/jQuery: Follow path over page

    - by Echilon
    I need to make an animated gif 'fly over a page and follow a path. I'm thinking of using jQuery but would I be right in thinking the only way to do it is manually calculating the percentage of width/height where the shape layer should be placed, then using absolute positioning is the only way to do this? I know there are some amazing jQuery plugins available for this type of thing.

  • How to disable scaling in JFreeChart?

    - by Alex Arnon
    Hi All, We're using JFreeChart to build an engine to display graphs. This is a web service that runs on Tomcat + Java 1.5.0, and renders charts to PNGs and JPEGs (using ChartUtilities.writeChartAs{PNG,JPEG}() ). We've run into a problem where JFreeChart seems to scale everything inside the Plot area, but only by a few pixels. The result is that the graph looks inconsistent, e.g.: Minor ticks are sometimes stretched horizontally, so that they seem to be two pixels wide instead of one. We use a small image in the top-right of the plot area as a watermark. This is stretched by one pixel horizontally and vertically somewhere near (but not exactly) its middle. Background grid lines seem to appear on sub-pixel boundaries. I have not found a way to create an accurately dotted grid line. We have tried both 1.0.9 and 1.0.13, with exactly the same results (except for the minor ticks, which were not available in the older version). Also, rendering the image to a Frame instead of JPEG/PNG produced an identical result. Help is greatly appreciated, in advance :)

  • Disable comments in stdout (DOS)

    - by Shadi
    If I use Dos command "copy" to concatenate two files: copy a1.txt + a2.txt a.txt I will have something like the following in stdout: C:\a1.txt C:\a2.txt 1 file(s) copied. I do not want to have anything written in stdout, I mean, I just want to have 'a.txt' without those 3 lines written in stdout. Is there any way to do so? the reason is, I need speed and I know that any IO takes time. Thanks, Shadi.

  • Rotate using a transform, then change frame origin, and view expands??

    - by ZaBlanc
    This is quite the iPhone quandry. I am working on a library, but have narrowed down my problem to very simple code. What this code does is create a 50x50 view, applies a rotation transform of a few degrees, then shifts the frame down a few times. The result is the 50x50 view is now much larger looking. Here's the code: // a simple 50x50 view UIView *redThing = [[UIView alloc] initWithFrame:CGRectMake(50, 50, 50, 50)]; redThing.backgroundColor = [UIColor redColor]; [self.view addSubview:redThing]; // rotate a small amount (as long as it's not 90 or 180, etc.) redThing.transform = CGAffineTransformRotate(redThing.transform, 0.1234); // move the view down 2 pixels CGRect newFrame = CGRectMake(redThing.frame.origin.x, redThing.frame.origin.y + 2, redThing.frame.size.width, redThing.frame.size.height); redThing.frame = newFrame; // move the view down another 2 pixels newFrame = CGRectMake(redThing.frame.origin.x, redThing.frame.origin.y + 2, redThing.frame.size.width, redThing.frame.size.height); redThing.frame = newFrame; // move the view down another 2 pixels newFrame = CGRectMake(redThing.frame.origin.x, redThing.frame.origin.y + 2, redThing.frame.size.width, redThing.frame.size.height); redThing.frame = newFrame; // move the view down another 2 pixels newFrame = CGRectMake(redThing.frame.origin.x, redThing.frame.origin.y + 2, redThing.frame.size.width, redThing.frame.size.height); redThing.frame = newFrame; So, what the heck is going on? Now, if I move the view by applying a translation transform, it works just fine. But that's not what I want to do and this should work anyway. Any ideas?
